Hemorrhagic cerebrovascular disease.

Area of Science:

• Neurology
• Radiology
• Neurosurgery

Background:

• Intracerebral hemorrhage (ICH) constitutes 10-15% of all strokes, presenting a significant mortality risk.
• Associated intraventricular hemorrhage increases 1-month mortality to nearly 50% and 6-month dependency to 80%.

Purpose of the Study:

• To review current neuroimaging approaches for intracerebral hemorrhage (ICH).
• To present a differential diagnosis of etiologies and imaging findings for primary and secondary intraparenchymal hemorrhage.

Main Methods:

• Review of current neuroimaging modalities including computed tomography (CT), magnetic resonance imaging (MRI), and digital subtraction angiography (DSA).
• Analysis of imaging manifestations for differential diagnosis of ICH etiologies.

Main Results:

• Neuroimaging is critical for identifying ICH etiology and informing therapeutic decisions.
• Active bleeding and potential hematoma expansion in the early hours post-ICH onset are key research areas.

Conclusions:

• Effective use of neuroimaging (CT, MRI, DSA) is vital for managing patients with spontaneous intracerebral hemorrhage (ICH).
• Ongoing research focuses on identifying patients at risk for hematoma expansion for targeted therapeutic trials.
